People occupying the coast of southern Peru 10,700 years before the present hunted shore birds and some fishes such as anchovies. These data suggest a coastal migration of people from Asia. This work was conducted by Susan deFrance and is reported in the journal Science. Related to this study is research by Elizabeth Reitz on the fish remains from a series of Archaic sites along the Peruvian coast indicating environmental changes during the early occupation. She identified fishes typically found in warmer water much further south than their present distribution.
